Cycle render noise wont change
I see that You set render samples to only 10 but used an emission node.. so I suppose You are trying to get a shadeless material..

the correct node setup for this kind of result is this:



don't really need for a 100 emission size, just 1 to 3 ^^

If You are trying to reach a different kind of result so... raise up your samples to 200 up to 1000 to archive much better results in cycles :)
